BRIEF  SUMMARY OF HISTORICAL ACCIDENT 

Within a year of King Gojong's accession to the throne, representatives of Meiji Japan appeared in Seoul to demand that the Koreans pay tribute. They also requested to make treaty to get in to the Chosun easily. Behind back of their mind, by making treaty, they wanted to dominate the Chosun. However queen min kept making relationship with Russia to prevent japan's power. Japan's agents and officials in Seoul, well aware of Queen Min's appeals to Russia, countered by approaching her old nemesis and father-in-law, the Taewongun. 

In the fall of 1895, Japanese ambassador to Korea Miura Goro formulated a plan to assassinate Queen Min, a plan that he named "Operation Fox Hunt." Early in the morning of October 8, 1895, a group of fifty Japanese and Korean assassins launched their assault on Gyeongbokgung Palace. They seized King Gojong, but did not harm him. Then, they attacked the queen consort's sleeping quarters, dragging out the queen and three or four of her attendants.

The assassins questioned the women to make sure that they had Queen Min, then slashed them with swords, stripped, and raped them. The Japanese displayed the queen's dead body to several other foreigners in the area, particularly the Russians, so that they knew their ally was dead, and then carried her body to the forest outside the palace walls. There, the assassins doused Queen Min's body with kerosene and burned it, scattering her ashes.

쓸쓸한 달빛 아래

내 그림자 하나 생기거든

그땐 말해볼까요 이 마음

들어나 주라고

문득 새벽을 알리는

그 바람 하나가 지나거든

그저 한숨쉬듯 물어볼까요,

나는 왜 살고 있는지

나 슬퍼도 살아야 하네

나 슬퍼서 살아야 하네

이 삶이 다 하고 나야 알텐데

내가 이 세상을 다녀간 그 이율

나 가고 기억하는 이

나 슬픔까지도 사랑했다 말해주길

흩어진 노을처럼

내 아픈 기억도 바래지면

그땐 웃어질까요 이 마음,

그리운 옛일로

저기 홀로선 별 하나

나의 외로움을 아는건지

차마 날 두고는 떠나지 못해

밤새 그 자리에만

나 슬퍼도 살아야 하네

나 슬퍼서 살아야 하네

이 삶이 다 하고 나야 알텐데

내가 이 세상을 다녀간 그 이율

나 가고 기억하는 이

내 슬픔까지도 사랑하길 우우~

부디 먼 훗날

나 가고 슬퍼하는 이

나 슬픔속에도 행복했다 믿게…

English ::

Undermeath the cold moonlight

If I can see my shadow lying there

shall I just tell you how I feel inside all thet is in my heart~

If the wind may blow on my heart,

telling me again thar I'm alone

should I just give out a sigh and ask myself

why do I have to live myself

though I may be sad I've got to live

because I feel so sad I must go on~

I know that I will understand when I'm gone

why I just had to live my life here in this world~

you were the only one for me~

though sorrow of my heart you loved me so~

please tell me so

like the evening light so falls

If all my memories just fade away

will I hold on to joy that's in my heart

oh,days of long a go~

wonder if the star in the sky

he know hoe I feel,my loneliness

maybe that is why he is there withme

he just there all through the night

though I may be sad I've got to live

because I feel so sad I must go on~

I know that I will understand when I'm gone

why I just had to live~ my life here in this world~

you were the only one for me~

though sorrow of my heart you loved me so~oh,

I hope some day

you were the one to cry for~

me that made me full of joy though I was sad~

my love
